background & aim: elaeagnus angustifolia and elaeagnus orientalis have a lot of medical utilization. in folk medicine, the fruit and flower of these plants are used as a tonic and antipyretic agent. the aim of the present study was to chemical analysis of volatile constituents of e. angustifolia and e. orientalis flowers.  experimental: the essential oils of e. angustifolia and e. orientali...

The prospect of using cocos nucifera Oil for production of biodiesel via transesterification reaction was investigated. The use of ethanol for the transesterification reaction instead of methanol was also evaluated. Test quantities of biodiesel were produced using 100 g, 20.0% and 0.8% of </span...

      The fruit of Melia azedarach L. (Meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using GC/MS. Thirteen components representing 85.1% of the total extract were identified. The major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). The fruits’ extract had a LC50 of 5.5 ppm agai...

essential oils (eos) extracted from aerial parts of aster indamellus grierson, calamintha umbrosa benth. and erigeron annuus (l.) pres.were analyzed by gc, gc/ms. the major acetylenic constituent (cis-lachnophyllum ester) of e. annuus was isolated and characterized by 1h and 13c-nmr spectra. their toxicity and repellent effect against lipaphiserysimi was tested. oils of e. annuus and c. umbrosa...

In this study, the non-catalytic supercritical method has been studied in utilizing dimethyl carbonate. It was demonstrated that, the supercritical dimethyl carbonate process without any catalysts applied, converted triglycerides to fatty acid methyl esters with glycerol carbonate and citramalic acid as by-products, while free fatty acids were converted to fatty acid methyl esters with glyoxal....

This work evaluated the process for heptaldehyde, undecylenic acid and methyl undecenoate production from castor oil, ester of oil ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that might be obtained by thermal cracking oil. Transesterification produces ricinoleate its generates heptaldehyde. The...

Increased energy consumption and the depletion of petroleum reserves have pushed up oil prices globally. Diminishing reserve is another global risk factor. ProducingBiodiesel vegetable oils animal fat by transesterification can be a considerable alternative. In this study, biodiesel produced from waste cooking method with methanol in presence HCl as catalyst. Biodiesel production begins mixing ...

A number of studies currently focus on the renewable fuels to reduce the reliance on petroleum fuels. Biofuels such as biodiesel and bioethanol have been studied and tested in many countries including India. This paper is aimed to investigate the performance and emission characteristics of a direct injection (DI) diesel engine when fuelled with methyl ester of Jatropha oil (MEJO). The ignition ...

The study investigates the effect of aluminium oxide nanoparticles as an additive to Madhuca Indica (mahua) methyl ester blends on performance, emission analysis of a single-cylinder direct injection diesel engine operated at a constant speed at different operating conditions. The test fuels are indicated as B10A0.2, B10A0.4, B20A0.2, B20A0.4 and diesel respectively. The results indica...
